^ Again, WoW does NOT support multithreading. So look at the physical core numbers only.

AMD for value, especially on low end. Most Intel CPUs will comparatively blow AMD out of the water, especiall threadrippers, but this is mostly down to single core, or at most 4 cores.

What you write doesn't seem to make any sense. Windows shuffles wow clients to hyperthreaded cores as well, if you have enough open clients. Each client does not have support any multithreading itself, that is not mandatory.

Performance wise and technically a Ryzen 7 or a Threadripper is superior to Intels mainstream and enthusiast CPUs in the case we look at here because of core and thread count.

I kinda went for the setup in my first post, and I am pretty happy with it. Although the AMD processors would have been better for the boxing I went for the I7-8700k since I will not box forever and the I7 8700k is beast.

The 32GB ram is total overkill. Should have gone for 16gb. But who knows what happens in future...

It is funny to actually see an increase of use on my GPU now my CPU handles a shit load more. The I7-8700k handles 20 clients perfectly running at 100% cpu usage. My cores reach max temperatures of 50-60 degrees Celsius. The GPU runs at 70-80%.

I still experience a few problems though. It seems to have something to do with my internet connection. Especially when I am boxing in a raid with others and especially when fixing raid groups I get insane lag spikes which make me drop connection from time to time, completely disconnecting me from the internet too. I noticed I am using a CAT5e cable so I order a cat6 to see if 100Mhz to 250Mhz imrpoves anything.

@Atreyyo: are you sure the background fps of WoW vanilla can be changed like this? You tipped me adding a line in the config.wtf file But it does not work. It seems vanilla WoW does not support maximizing fps. Making Windows smaller in the background seems to help.

Two questions:

1 I am currently at 200mbs/20mbs internet speed. Would increasing to 400mbs/40mbs help smoothing the boxing? Would a CAT6 UTP or better change anything?2 Any way without ISboxer to lower CPU/GPU usage by lowering frame rate on the clients? I am 60+ now constantly.

I really doubt the problems are caused by having too less bandwidth in your local network or to the internet.I've been running around in Badlands minutes ago and WoW used about ~600-1000 Bytes/s up and down combined. Given a conservative estimate I'd multiply by 20 for bossfights so we're at 20 KBps. Times 20 for all your clients is 400 KBps.I guess having the server throttle you due to your shared IP address will cause troubles before anything else.Would love to see some real-world numbers of your setup

@Pucchini so you are saying using the same IP for all boxers can lead to issues aswell? Can you explain that?

With totally internet shutdown I mean my computer is unable to connect to the internet after the disconnect happens and I need to restart the computer.

The thing which is strange to me is that I have played 29 characters at the same time in Molten Core without any freezes and smooth as fuk and I have done full ZG in less than 1,5 hour and at the same time I can experience those issues with complete freeze and connection loss when playing 10 chars in a 40 man raid.

Regarding your question. Under my current settings the I7 8700k is at 100% when boxing 20 chars. Although at 29 chars there is No notable difference.

when i boxed 5man frostmaul giant farm groups, sometimes each client would have a different latency, e.g 30ms, 200ms, 500ms, 1.5k and one client that completely lags out, some restarts fix that, but it's really weird, i dont have internet issues, running on a 100mbps fiber

@Pucchini so you are saying using the same IP for all boxers can lead to issues aswell? Can you explain that?

WoW Servers do have "command" throttling as a flooding protection, e.g. addons and chat messages are limited by a threshold of ~3000 commands per second.The only thing I dunno is if that's per client/char, per IP, per machine etc.
